我正在尝试为 Django 编写一个“仅限员工”的装饰器，但我似乎无法让它工作：
def staff_only(error='Only staff may view this page.'):
def _dec(view_func):
def _view(request, *args, **kwargs):
u = request.user
if u.is_authenticated() and u.is_staff:
return view_func(request, *args, **kwargs)
messages.error(request, error)
return HttpResponseRedirect(request.META.get('HTTP_REFERER', reverse('home')))
_view.__name__ = view_func.__name__
_view.__dict__ = view_func.__dict__
_view.__doc__ = view_func.__doc__
return _view
return _dec
尝试去从这里跟随线索 http://passingcuriosity.com/2009/writing-view-decorators-for-django/。我越来越：
'WSGIRequest' object has no attribute '__name__'
但如果我把这 3 行去掉，我只会得到一个无用的“内部服务器错误”。我在这里做错了什么？
该装饰器已经存在
from django.contrib.admin.views.decorators import staff_member_required
@staff_member_required
